INSECTICIDAL N,N'-DISUBSTITUTED-N-N' -DIACYLHYDRAZINES BACKGROUND OF THE INVENTION This invention relates to N,N'-disubstituted-N,N'-diacylhvdrazines which are useful as insecticides, compositions containing those compounds and methods of their use. This invention also relates to the production of intermediates useful in the production of such compounds.
The search for compounds which have a combination of excellent insecticidal activity and low undesirable toxicity is a continuing one because of factors such as the desire for compounds exhibiting greater activity, better selectivity, lower undesirable environmental impact, lower production and market cost and higher effectiveness against insects which are S or become resistant to many known insecticides.
There continues to be a need to develop insecticidal compounds having improved 15 insecticidal and methods of production properties as described above. The present invention provides improved N,N'-disubstituted-N,N'-diacylhydrazines which are unexpectedly propertied with enhanced, higher activity. The combination of higher activity and lower undesirable toxicity can provide an economic and environmental advantage in the use of the inventive compounds. Compounds of the present invention are particularly suitable for 20 controlling plant-destructive insects in crops of cultivated plants, ornamentals and forestry.
U.S. Pat. No. 5,117,057 discloses insecticidal N'-substituted-N,N'-disubstituted hydrazines and Japanese Kokai Hei 4-235177 discloses new hydrazine derivatives and their use as the effective ingredient in insecticide compositions.
SUMMARY OF THE INVENTION In accordance with the present invention there are provided insecticidal compounds having the formula: 0 R 2 z C-N-N-C-0 (I I II wherein: R' is cyano or a hydrogen atom

METHODS OF PREPARATION Many of the compounds of the present invention, and the intermediates related thereto, can be prepared by methods similar to the known methods, such as those taught by US Pat. No. 5,117,057, for making N,N'-disubstituted-N,N'-diacylhydrazines. In particular, Process B Method 2 was used to prepare the compounds of Table 1. Those of ordinary skill in the art will be able to utilize or modify such processes after knowledge of the disclosures herein to 14 accommodate many of the functionalities RI, R 2 Ra, B and Z in the intermediates and compounds of the present invention. The agronomically acceptable salts of the present insecticidal compounds can be synthesized by the utilization of the salting methods known in the art relating to N'-substituted-N,N'-diacyhydrazines used as insecticides.
Preparation of 6-carbo2yMethyl-2,2-dimnethyl-di hydrob enzofu ran and 6carb oxymthyEl,:methyl-benzo fu ran Using procedures analogous to those of D. W. Robertson, et. al., J. Med. Chem., 310 (1992) and V. Peesapati, and N. Lingaiah, Org. Prep. Proc. Int., 24(11127 (1992), the hydroxy group of methyl 3-hydroxybenzoate was alkyla ted with 3-chloro-2-methyl-1propene to give methyl 3-(2-methyl-2-propenyloxy)benzoate. This material then OL 0 underwent a 3,3 sigmatrophic shift to give methyl 3-hydroxy-4-(2-methyl-2- **s propenyl)benzoate. Formic acid catalyzed ring closure resulted in 2,2-dimethyl-6carboxymethyl-dihydrobenzofuran.
By using 2,3-dichioropropene instead of 3-chloro-2-methyl-l-propene as the alkyla ting agent, the same procedure provides 6-ca rboxyme thyl1-1 -methyl-benzofuran.
Preparation ot 6-Carboxy-benzofuran and 6-Carboxy-dihydrobenzofurari 6-Carboxy-benzofuran was prepared from methyl 4-formyl-3-hydroxy-benzoate 0 using the procedure of F. Duro and P. Condorelli, Anti. Chim. (Rorna), 53(11), 1582 P0 (1963). The corresponding dihydrobenzofuran was prepared by catalytic hydrogenation of the benzofuran in a Parr apparatus using ethyl acetate as the solvent 9 and platinum oxide catalyst.
Preparation of 7-substi tuted-6-carb ox-di hydrob enzo f uran 6-Carboxy-dihydrobenzofuran was first treated with thionyl chloride to give the acid chloride. The acid chloride was then treated with 2-amino-2-methylpropanol. to give an intermediate amide which was cyclized to 6-(4,4-dimethyl-2-oxazolyl)dihydrobenzofuran by treatment with thionyl chloride, both steps using the procedure described in A. Meyers and W. Avila, I. Org. Chem., 46, 3881 (1981). This procedure also describes methylation at the 7-position using butyl lithium and methyl iodide.
Subsequent acid catalyzed hydrolysis of the oxazoline results in formation of the 7substituted-6-carboxy-dihydrobenzofuran.
Preparation of 7-substitute&, 'its2-substituted-6-carbox -benzofurans 6-Carboxy-benzofuran was treated with 2.2 equivalents of butyl lithium in tetrahydrofuran at -65 to -70'C followed by addition of ethyl iodide and permitting the reaction mixture to warm to room temperature. This process resulted in a mixture of the 7- and 2-ethyl substituted 6-carboxy-benzofurans. These two isomers were not separated at this time. However, after formation of the corresponding N-substituted- N,N'-diacylhydrazines, as described below, the isomers were separated as the diacyihydrazine derivatives using silica gel chromatography with methylene chloride:ethyl acetate 9:1 elution solvent.
Preparation of N-su bstituted-NN'-diacylhydrazines The N-substituted-N,N'-diacylhydrazines corresponding o the above carboxybenzofurans; were prepared in a two step process. The first step is the .:7 life:formation of the acid chloride. With the exception of 2,2-dimethyl-6-carboxy- 0*@O dihydrobenzofuran, which required the use of oxalyl chloride, the acid chlorides can be :prepared using standard methods known in the art using thionyl chloride, oxalyl 15 chloride, phosphorous pentachloride, and the like, as the chlorinating agent.
Reaction of the acid chloride with hydrazine -in an inert solvent such as dichioromethane or butyl acetate and potassium *carbonate resulted in formation of the corresponding N-substituted-N,N'diacylhydrazines of formula I wherein' the Z substituent forms a fused furan or 0:20 dihydrofuran ring.
